Selecting A Random Row Of A Mysql Query Result?
Let say I have a mysql query, which might yield more than 1 row when queried. How can I set up the query, so that it RANDOMLY selects one of the results? I know that I can do a LIMIT 1 command, but this will always yield the first row.

Selecting Only Part Of MYSQL Result
Ok I am writting a script where the first time you look at something it inserts a word, on that shouldnt be mistakenly typed in. The script is pulling from a MySQL DB. I need to have a way to check for the word and if present not readd the word so it doesnt replicate over and over again. echo "<TEXTAREA name="comments" rows="8" cols="20">$displaycall[9] TheWord:</TEXTAREA>"; What is happening right now every time this updated it adds TheWord: over and over again. Any ideas how to check inside of the $displaycall[9] for TheWord:?

Selecting A Mysql Row Set In A Random Order
I have implemented a links bar on the side of a site, which I want to popuplate with links from a database randomly, but I feel the php workaround I used is inefficient. Is there a way to randomize the result in a mysql SELECT query? "SELECT * FROM links ORDER random" I know the code above is probably way off, but it illustrates what I want I think.

Same Mysql Query Doesn't Always Return A Result
We have no access to a mysql NG on my provider's server, so we ask here: We have a long query (long in text) with a UNION between 2 select. We have been informed that some times the query doesn't return any result. We have tried on our server and we always get a result. BUT, trying on the hosting server, many times the query doesn't return any result and doesn't get any error. Any idea ? does Union have any problem ? how to check if the query failed ? My hoster said that sometimes the table can be locked (if the server is overloaded) and then mysql doesn't return any result, but this seems to me an aberration. the query takes about 0.0050 sec to execute when it doesn't return any result, and 0.030 when I get results

MySQL Query Result Rows
Still learning the ropes of PHP/MySQL here so pardon if this is something from a 101 class. I am wanting to know if/how I can query a MySQL database, pull two rows of information and assign them individual variable names. I know this isn't too clear. Let me try to explain what I want to do. Let's say I have something similar to this: Code: $query = mysql_fetch_assoc(mysql_query("SELECT entry_id, user_id, date FROM my_entries WHERE user_id = '$user_info[user_id]' ORDER BY date DESC LIMIT 2")); What I would like to be able to do is assign separate variables for the info on the two rows returned by the query. I want to have the following variables: $first_date = $query[date]; <= from the first row $second_date = $query[date]; <= from the second row I can then use the two variables to compare to each other, etc. Can this be done with a single query? Or are two queries required (if so how)?

How To Get Mysql Query Result Into Temp. Txt File
I did a lite search in the archive but didn't find anything specific to my problem. Here is what I am trying to do: I've got a table with about 25k entries of company addresses. I need to be able to pull specific data out of the table and put it in a temporary text file and then display the result in the browser for the user to save locally. The query part and the format of the data is all simple enough but I am having trouble figuring out how to get the data from the query into a temporary text file and then displaying that file. here is what I whipped up but it obviously doesn't work: Code: <? $tmpfname = tempnam("/path/to/file/", "FOO"); $list = mysql_query("select * from FH_LIST where State='AK'"); while ($list_results = mysql_fetch_array($list)) { $data = blah blah blah; fwrite($tmpfname, ".$data "); } fopen($tmpfname, "r"); fpassthru($tmpfname); ?> I get an error message saying: Warning: Supplied argument is not a valid File-Handle resource (referring to $data).

Random And Query
I am trying to write a piece of code that will enable me to get one peice of information based on the last piece of information returnted from a mysql db. Sounds unclear but here is what I mean. PHP Code: $query = "SELECT * FROM timetable where departure = 'EGNT' ORDER BY RAND() Limit 1 "; it returns the data EGLL as the next departure for example so I now wish to see random items with a departure from EGLL. Now I am wondering is there a faster way to create maybe 6 of these situations as aposed to having to right 6 queries based upon the departure result of the last ie all in one query based upon the result of the last or am I confined to seperate queries on this on.
